The DLVO theory has been widely used to study the stability of colloidal systems with the van der Waals interactions modeled according to the Hamaker (microscopic) theory. The Hamaker theory, in addition to neglecting many-body interactions, does not account for retardation effects. Retardation effe

## NOTE The Van der Waals Free Energy of an Oil-Water Pair in a Multilayer An expression for the van der Waals free energy of an oil-water multilayer per one pair of oil-water lamellae is derived in the hypothesis of pairwise additivity. The formula has the expected symmetry in the thicknesses of
The van der Waals interaction between perfectly spherical, infinitely hard spheres is well understood. Unfortunately, real powder particles are not infinitely hard and rarely spherical. Those particles that are approximately spherical are often covered in small asperities. It is often believed that
